BED-LOCK.

Specification of Letters Patent.

Application filed August 28, 1912. Serial No. 717,513.

T 0 all whom it may concern:

Be it known that I, V ALTER B. SwinincLL, a citizen of the United States, residing at Raleigh, in the county of Wake and State of North Carolina, have invented new and useful Improvements in Bed-Locks,ofwhich An embodiment of the invention is illusrated in the accompanying drawings, wherein Figure 1. is a front elevation of one end piece of a bedstead equipped with the improved clamps, the side rails appearing in section; Fig. 2 is a horizontal section taken on the line Q2 of Fig. 1; Fig. 3 is an enlarged perspective View of the clamp, 7767' so.

lnsaid drawings, the end piece A, which may be either the head or foot piece, as will be understood, consists of the usual uprights or legs 5 which are connected by the usual upper cross-pieces (3 and the end. rail 7. These parts may have any preferred construction.

The side rails 8 are connected to the uprights 5 by means of the improved clamps B which preferably com-prise fixed'and movable jaws 9 and-10 designed to be fastened together against the end rails 7. In the construction shown in the drawings, the fixed jaw of the clamp has substantially the form of a right-angle and consists of the two wings 9 and 9 and the connecting or apex portion 9 which latter is of concavo-convex formation, so as to fit against the adjacent upright. The wing 9 is riveted, or otherwise rigidly fastened to the inner face of the adjacent side rail, at the end-thereof, as shown in Fig. 3, while the wing 9 is disposed against the inner face ofuthe adjacent end rail 7. 'The movable jaw/"10 is hinged at its inner end to the concave-convex terminal portion 8 of the side rail and itself comprises a similar portion 10 and a fiat portion 10 the first-named portion cooperating with the portions 8 and 9 in form mg a; sleeve or socket. which encircles the upright. The Hat portion 10 of the znov- Patented Nov. 26, 1912:.

able jaw designed to fit flush against the outer face of the end rail, and that portioi'i, and the corresponding portion or wing 9" of the fixed jaw are removably fastened together and to the end rail by suitable'devices, here shown as consisting of a threaded bolt 11 which is passed. through registering openings 10 7 and 9* in the three parts in question, and is provided witl'i a. wing mat 11 designed to be tightened against the part 9 The opening 10 is adapted to receive the head of the bolt, while the openings and 9* are in the form of slots through which the stem of the bolt projects, the "lot 7 extending a short distance beyond the jacent end of the slot 9*, which latter opens through the edge of the win 9?, so as to facilitate the withdrawalof the bolt when the momble jaw is swung outwardly away from the end rail.

To support the clamp and, also, the side rail, the upright 5 is provided-with a collar 19. which is securely fastened thereto and is formed upon one side with a pair' of spaced. upwardly-projecting lugs I2 as shown in Figs. 2 and 3. The upper portion of this collar constitutes a'support upon which the lower edges of the three concavo-convex parts 8 9 and 10 of the clamp directly rest, and the lugs 12- are so arranged as to straddle or project across opposite sides of the part or wing 9 and the adjacent portion of the side rail, thus constituting stops which positively preclude lateral movement of the rail and clamp.

From the foregoing, it will be at once apparent that the clamp is simple in its construction, and correspondingly inexpensive to manufacture; can be readily applied to and removed from any head or foot piece of a bedstead of conventional type; and, when so applied, will be perfectly supportechby the collar, which latter can be readily raised or lowered, to adjust the height of the rails.

convex portion vhinged at its free edge to that of the first-named concavo-convex portion and a flat portion arranged against the outer face of the end rail, and a fixed jaw comprising a pair of fiat portions and'a conoavo-convex connecting portion, one of said flat portions being arranged against the inner face of said side rail and the other against that of said end rail, and means for removably connecting the fiat portion of said movable jaw and the said other flat portion of said fixed jaw to each other and to said end rail, the concavo-convex portions of said side rail and said fixed and movable jaws cooperating to form a sleeve which encircles the adjacent. upright.

2. The combination, with an upright and I side and end rails of a bed; of a collar secured to said upright, a clamp secured to said side rail and comprising fixed and mov-' able jaws resting upon said collar, said jaws engaging said upright and the opposite faces of said end rail, a pair of lugs carried by said collar and engaging said side rail and, said fixed jaw for holding the same in place,

and means for removably connecting said jaws to each other and to said end rail.

3. The combination with an upright and side and end rails of a bed; of a collar secured to said upright, a clamp carried by said side rail and resting upon said collar, said clamp engaging said upright and said end rail, and retaining means carried by said collar and engaging said side rail and clamp.

1-. The combination with an uprightand side and endrails of a bed; of a collar 5%- cured to said upright, a clamp carried by said side rail and resting upon said collar, said .clamp engaging said upright and said end rail, and a pair of retaining lugs carried by said collar and engaging said side rail and clamp.

In testimony whereof I havehereunto set my hand in presence of two subscribing wit- Witnesses:
